A 150mm is a large artillery Shell which is used in late-game artillery weaponry.
Description
150mm is a large artillery shell that is fired over long ranges.
Like other artillery shells it is indirect fire: it has a natural inaccuracy which increases with range, its trajectory is affected by the wind, and it can trigger the retaliation of Artillery Garrisons. Exceptionally, it is used in direct fire mode by large guns on Battleships.
It explodes on impact. The explosion deals 900 High Explosive damage in a 7m radius and decreasing amounts in a 11.25m radius. The explosion leaves a mark on the ground that devastates the ground much more than 120mm and can sometimes produce large Craters.
It's effective against most structures but less against very resistant ones, and awful against Trenches. It is mediocre against armored vehicles and its innacuracy makes it hard to hit a mobile target. It can disable their subsystems (the tracks in most cases). It can kill infantry and unarmored vehicles although that isn't cost efficient.
Whereas 120mm is the go-to shell to destroy Tier 1 and Tier 2 structures, 150mm is often used to siege concrete, and other structures with higher resistances due to its increased damage.
It has a chance to turn into ruins Garrisoned Houses that suffer from devastation when dealing the killing blow.
As a Large Item, the player can only carry one in their large item slot, occupying their hands. It is automatically dropped if the player draws a weapon or equipment.
Its weight is reduced by 33.3% when wearing a Heavy Ammo Uniform.

Users
It can be fired by the following infantry weapons, vehicles, and structures:
• 50-500 “Thunderbolt” Cannon 
• Callahan 
• Flood Mk. IX Stain 
• Huber Exalt 150mm 
• Lance-46 “Sarissa” 
• Titan 
Production
Tier 2 Facilities must be fully researched in the Weapons and Structure 
Tech Tree in order to be produced.
150mm in Facility personal orders can be retrieved as reservable crates from a logistics vehicle with 
> Retrieve as Crates (5 per crate).
Mass Production Factory orders must have at least 3 crates.
Storage
It does not stack in inventories (1 per slot) except in ammo slots dedicated to it in certain vehicle or structure inventories (varying stack sizes).
It can be stored in the stockpile of Bases (32k max) but also in Material Pallets (120), Material Transfer Stations (1000), Rooster - Tumblebox Trailer (32), Small Flatbed Car (100) or Storage Rooms (100).
Crates of 150mm can be directly submitted to any item stockpile that accepts that item to transfer their content. The crates can also be stored in the crate stockpiles of Storage Depots (1000 public, 100 per Reserve Stockpile), Seaports (1000 public, 100 per Reserve Stockpile), Shipping Containers (60), or Storage Ships (1000).
It can be transported by almost any vehicle with inventory slots, but is most commonly transported by Trucks, Small Flatbed Car, or shipping vehicles carrying Material Pallets. It can also be transported as crates, either delivering them to a Base's stockpile with a Truck or to a crate stockpile with shipping vehicles carrying Shipping Containers.
